Subaru OBW a pillar insert

So I installed a dashcam in my wifes Outback and later on she had the windshield replaced. after that the a pillar would constantly pop out. So I did a little measuring and designed this insert for the A pillar top barb receptacle. What appears to be the issue is that the barb insert on the A pillar has been slightly crushed and so it does not provide enough friction.

inserting this into the A pillar trim hole adds more resistance to keep it in. so far my wife, that couldn't go one trip to work without it popping loose has gone 4 days. so fingers crossed.

This is the 11th time i have iterated it. if you need to change something there is a tinkercad link below. The two objects are the part and a barb simulator.

This needs to be printed out of TPU. I tried with a 0.6 nozzle in my revo and it did not turn out well. So i moved down to a 0.4, 0.25 might be even better. 0.2 layers should result in two layers for the bottom. which will then not collapse when putting it into the h
